Hub nut sizes (probably a very daft and obvious question)

[tired and confused]

Hey all, i'm doing a gearbox change on my 1.6 Driver as the layshaft bearing has shagged itself out and I need to get the hubs loose to get the driveshafts out.

Now, what size is the hub nut as i don't have a socket thats fits and GSF weren't able to help either

p.s. This is probably a very daft thing to ask

[russ-vdub]

measure it

30mm.

[tired and confused]

measure it

I did but tape measures aren't that accurate when doing it by eye, Verniers are much better but I don't have any

Cheers btw Diamond, it's back to the autofactors for me then!

If you're in Bristol I have one and a breaker bar.  I'm quite happy to offer their use, if convenient.
